Willem Fredrick Proost
Founder
Est. 1979
Willem Fredrick Proost looked at what South African laboratories were being offered — and wasn't satisfied. Rather than wait for someone else to fix it, he took responsibility and built the alternative himself. In 1979, Labex was born out of that refusal to accept good enough. That same standard is still here today.
“Fifty years in, and the belief hasn't changed: science should serve people, not the other way around. Behind every result is someone who needed it to be right. Every smile counts — and we've never lost sight of that.”

What we stand for
Technical depth over sales spin
Our team understands the science behind what we sell. Ask a technical question and you get a technical answer — not a brochure.
Long-term relationships, not one-off orders
We've supplied the same research institutions and manufacturers for decades. That's what happens when you consistently deliver what you promise.
After-sales is part of the deal
Internationally trained service technicians on staff. When something needs attention, we fix it — no outsourcing, no queues.
